UNITED STATES PATENT orrron. JONAS NORTHROP, OF HOP EDALE, MASSACHUSETTS, ASSIGNOR TO DRAPEB, COMPANY,

I OF HOPEIDALF. MASSACHUSETTS, A CORPORATION OF MAINE,

THREAD-PARTER roe Looms.

Specification of Letters Patent.

Patented Nov. 11, 1913.

To all whom it may concern.

Be it known that I, JoNAs Non'rrmor, a

citizen of the United States, residing. at

Hopedale, in the county of Worcester and State of Massachusetts, have invented an Improvement in Thread-Parters for Looms, of which the following description, in con nection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

The inventionto be hereinafter described relates to that class of looms in which replenishment of the filling is automatically effected when necessary, and more particularly to the means employed for parting the filling ends at the changed side of the loom. In devices of this general character it is desirable that the filling ends, that would otherwise extend from the cloth selvage due to change of filling, be 'trimmedoif evenly and close to the selvage. On the one hand, due regard must be had to the desirability of parting thefilling end closely adjacent the cloth selvage, and, on the other hand, that the-means employed'be of a character that will not cut or injuriously act upon either the cloth or'its selvage. 1

With these general considerations in view, the aims and purposes of the present invention are to provide a parting device for the filling ends that will be simple in construction and yet will act effectively to part the filling ends close to the cloth selvage without liability of injuring either the'cloth or selvage, all of which will more clearly. ap-

pear from the following description and accompanying drawings of one form of means for carrying the invention into practical effect.

In the drawings: Figure 1 shows the present invention in side elevation and part of the lay as it moves forward under the usual lay actuating means; Fig. 2 is a front view of the parts shown in Fig. 1, the lay being omitted; Fig. 3 is a section on the line 3-3, Fig. 2; and Fig. i is a detail and a parting device, preferably formed as, a blade or blades, the construction being such that during the action of the parting device the cloth shall be so irely held at the selvage to insure proper action of the part ing device, and that thereafter the cloth may be released toenable the usual forward movement thereof as the weaving proceeds.

The present embodiment of the invention shows a jaw temple having the lower jaw 1, and the upper jaw 2 between. which the cloth passes. The upper jaw is hung from a stud shaft 3 by means of the sleeve 1 and link 5, which is pivotally connected to the upper 'jaw 2 by means of the lugs 6, 6 and pin 7. Projecting from the sleeveis an arm 8, Fig. 1, on which acts a spring 9 normally tending to turn the sleeve in a direction to close the upper movable ja'w 2 upon the lower fixed jaw 1. Mounted on the arm 8 is a rocking memberlO, preferably pivoted to the arm 8 at 11, Fig. 1, although it may be'otherwise formed. Pivotally mountedon the temple body at 12 is a wiper, which, just as the lay reaches its extreme forward position in its beat-up 'movement, wipes under the member 10 to raise and then release the arm Sand thereby separate the two jaws to temporarily release the cloth and then reclamp it. This wiper in the form of the invention shown comprises a member 13 having a roller 14:

to engage and disengage the rocking member 10, and a tail piece 15 adapted to be engaged by the lay as itreaches ts forward position orjust prior thereto.

A spring 16 disposed between the lug 17 i on the wiper and a lug 18 on the temple body serves to hold the wiper in normal position, asindicated in Fig. 1, ready to be actuated by the lay for operating the jaws in the manner already described.

The lay or lay beam 19 may be carried by the usual lay swords and be actuated in any usual manner, which being well un. derstood by those skilled in the art needs no further description. "In order to actu'- ate the wiper the lay 19 may-have a hunter 21, adjustable as by screw thread connection zwith the lay, as shown.

The jaw temple and its operating parts maybe as fully shown anddescribed in my prior Patent No. 956,725, dated May 3, 1910, and to'said patent reference may be had for mes o mote full and detaildestn'ijpv n of the 6"?1' and then ieclamp the cloth, as luueinbcfore strnetion and ope!
